    KGR Rotary Surface Grinder
    KGR 500/600/800/1000

    Features:

    Structure

    ● Castings are made of high quality ribbed cast iron, which have been heat-treated to achieve extreme rigidity. Major castings are all box-type designed for excellent rigidity and strength. Compact designed bed and columns enable the whole machine to be shipped in a regular container, and also much saving on ocean and inland freight.


    3-Axes Mechanism

    ● The “SP” grade linear guides are used for Y/Z axis, and there are four blocks on each axis that can provide 0.001mm vertical/cross-feed graduation.

    ● Vertical/cross-feed driven by AC-servo-motor.

    ● The hydrostatic rotary table with very low friction force and high rigidity, driven by servo motor with belt.


    Spindle

    ● Cartridge and flange type designed, powered with a powerful motor and supported by 3 sets of #7016 CP4 super precision angular contact ball bearings.


    Controller

    ● The well-known control system Mitsubishi PLC and servo motor. Ergonomically designed operation panel, with 10” colored touch screen for grinding data input through dialog pages. We use MPG instead of hand-wheel for precision and easy usage. Y-axis is equipped with “HEIDENHAIN” linear scale for a real closed loop feedback system.


    Dressing and compensation

    ● The table mounted wheel dresser is integrated into automatic grinding cycle. The dressing result is perfectly paralleled to table surface for super precision grinding applications.


    Lubrication

    ● Auto lubricating system ensures the slide ways and ball-screws are well-lubricated.


    Coolant systems

    ● Coolant tank type 250liter, 2bar, 80L/min
